天然砂石资源有限,大量使用这些资源也破坏环境。自燃煤矸石、矸石电厂炉渣是工业废料,推广煤矸石砂浆、商品干砂浆、矸石锚喷支护混凝土,改性矸石料商品混凝土掺用技术,不仅有经济价值,同时又有环境效益。本文结合煤矿区实际情况,介绍了用自燃煤矸石配制砂浆、自燃煤矸石集料锚喷支护混凝土、商品干砂浆、改性矸石粉砂浆、商品混凝土中的改性煤矸石粉利用技术。
Natural gravel resources are limited, extensive use of these resources also destroy the environment. Spontaneous combustion of coal gangue, gangue power plant slag is industrial waste, the promotion of coal gangue mortar, dry mortar products, rock bolting and shotcrete support concrete, modified gangue material mixed with concrete mixing technology, not only economic value, but also environmental benefits. Based on the actual situation in coal mining area, this paper introduces the technology of using coal gangue with spontaneous combustion of coal gangue, spontaneous combustion of gangue aggregate spray anchor support concrete, dry mortar, modified gangue powder mortar, modified gangue powder in commercial concrete .
